ROOF CLAMP OR BRACKET.

SPECIFICATION forming part of Letters Patent No. 713,061, dated November 11, 1902. Application filed February 13, 1902. Serial No. 93,949. (No model.)

To all whom it natty concern:

Be it known that I, IRA ELLSWORTH CLUM, a citizen of the United States, residing atLima, in the county of Allen and State of Ohio, have invented a new and useful Roof Clamp or Bracket, of which the following is a specification.

This invention is an improved construction of roof clamp or bracket, the object being to provide a cheap and simple and efficient de vice which can be quickly and easily attached to a shingle roof for the purpose of supporting the main cross-beams of a scafiold.

Another object of the invention .is to provide a bracket which can be used in connection with depending hooks for the purpose of supporting a swinging scaffold and with these objects in view the invention consists in the novel features of construction and combination hereinafter fully described, and pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a perspective view showing the'practical application of my invention. Fig. 2 is a sectional view of the same. Fig.- 3 is a view showing all of the parts detached and illustrating said parts in detail in perspective. Fig. 4 is a detail perspective View illustrating the socket attachment to the clamp and holder. Fig. 5 is a sectional View showing such attachment. Fig. dis a side elevation showing the mannerof using the depending hook in connection with the holder. In carrying out my invention I employ afla metal plate A, which is turned upwardly at its forward end, as shown at A, the extreme end of said portion A vbeing rounded or formed into a barrel, as shownat-A The rear end of the plate A is formed with barbs or supports A .which are adapted to engage the shingles or roof-sheathing for the purpose of holding the plate securely in position. A second plate B,which I design ate the upper plate, is of substantially the same Width as the bottom plate A and is bent upwardly, as shown at B, and then downwardly, as indicated at 13*, the forward end being rounded or formed into a barrel B The plate B at the juncture of the members B and B is formed with a central opening B the purpose of which will appear hereinafter. The

barrel portions A and B are pivotally connected by means of the links 0, pivot-bolts C and G passing, respectively, through the front andrear ends of the said pivots and through the barrel portions A and B An angular holding member D is pivoted in the opening B by means of a bolt or pin 0 passing through the holder D, produced in the vertex of the member D, said member having a forwardly-projecting finger D which limits the upward movement of the angular holding member by pressing upon the inclined portion B of the plate B, as most clearly indicated in Figs. 1 and 2.

A block E, having a socket-opening E, is

securely fastened to the plateB adjacent to the portion B by means of bolts E whenever it is desired to use my clamp or bracket in connection with depending hooks for the purpose of suspending a hanging scaffold. F indicatessuch hooks, the end F being fitted into the socket-block and the end Ff formed into an eye,fro m which the scaffold-ropes can be suspended. It will be understood that when the hooks F are used the angular hold ing members D are disconnected from the clamp or bracket.

In operation I employ two or more clamps or brackets, the plate A being inserted be neath one tier of shingles, while the plate B is inserted beneath the next adjacent tier of shingles. The cross beam ortimber Grests upon the plate B and is held in its proper position thereon by the angular holding member D, inasmuch asthe lower side of the said beam or timber bears against thejlower member, While the upperi'member presses firmly upon the top or side of the beam, as most clearly shown in Figs. 1 and 2. By having a pivotal connection between the forward ends of the upper and lower plates I am enabled to arrange the clamp or bracket in its proper position irrespective of-the ,size and thickness of the shingles or roof-timbers. When the angular holding member D is employed, the socket-block is removed from the plate 13. Having thusfully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A roof clamp orbracket, comprising two plates connected at their forward ends by a link connection, the upper plate carrying a socket, and a hook, the upper end of which the angular holding member and the socketis adapted to fit into said socket, substanblock adapted to be attached to the upper 10 tially as described. plate, substantially as specified.

2. A roof clamp or bracket, comprising the y A 5 lower plate bent upwardly at its forward end, IRA ELLSWOR 1 H OLUM' and an upper plate bent upwardly and then Witnesses: inclined downwardly, the forward ends of J. W. HALLER, said plates being connected by means of links, R. F. BENNETT.
